    Notes: Abstract A previously undescribed subfamily of mouse class I MHC genes, consisting of two to three members, has been identified. The structure and organization of one of these, Mb1, has been determined. Mb1, consists of five exons with open reading frames and potentially encodes a class I-like transmembrane protein. In the genome, Mb1 is linked to the H-2 complex, mapping telomeric to Qa. However, this gene has low (ca. 60%) nucleotide identity with other class I sequences and is no more related to mouse class I genes than to class I genes from other species. Mb1 transcripts have not been found in a variety of adult tissues or cell lines, suggesting that, if Mb1 is expressed, its expression is highly regulated. From DNA sequence identity and intron-exon organization, Mb1 appears to be a primordial gene which antedates mouse speciation and which has evolved independently of the rest of the class I gene family. Examination of various species of wild mice demonstrates the presence of a discrete Mb1 subfamily over long evolutionary periods of time.

    Notes: Abstract To examine the evolution of multigene families we have selected as an example an immunoglobulin light chain variable region subgroup (Vϰ24) which has been extensively characterized in inbred mice (Mus musculus domesticus). Homologous genes have been isolated and sequenced from Mus pahari, a genetically and geographically isolated species believed to be the oldest living representative of the genus. Southern blot analysis using probes corresponding to individual genes in this subgroup reveals changes in the overall size of the family occurring at the level of individual genes but not at the level of the entire family. Nucleotide sequence analysis indicates an absence of regulatory sequences such as the CAT and TATA boxes 5′ to the coding region, but a decanucleotide sequence involved in light chain expression is highly conserved. Within coding regions highly complex patterns of variation are seen which appear to reflect quite different selective pressures on various subregions of the coding sequence. Complementarity determining regions (CDR) are conserved to different extents, with the first CDR region in all family members being among the most conserved segments of the molecule. Conservation is similarly variable among framework segments, indicating complex and variable evolutionary pressures not only at the level of individual genes or their products but also at subregions within homologous molecules.

    Notes: The crystal structure of the Fab of the galactan-binding immunoglobulin J539 (a mouse IgA,κ) has been determined at a resolution of approximately 2.6 Å by X-ray diffraction. The starting model was that obtained from the real space search described previously (Navia, M.A., Segal, D.M., Padlan, E.A., Davies, D.R., Rao, D.N., Rudikoff, S. and Potter, M. “Crystal structure of galactan-binding mouse immunoglobulin J539 Fab at 4.5 Å resolution.” Proc. Nat. Acad. Sci. USA, 76:4071-4074, 1979). This Fab structure has now been refined by restrained least-squares procedures to an R-value of 19% for the 11,690 unique reflections between 8.0 Å and 2.6 Å. The rms deviation from ideal bond lengths is 0.025 Å. The overall structure differs from McPC603 Fab, another mouse IgA,κ antibody, in that the elbow bend, relating the variable and constant parts of the molecule, is 145° vs. 133° for McPC603. The region of the molecule expected to be the antigen binding site contains a large cavity with two clefts leading away from it. This has been fitted with a model of an oligo-galactan.
